Concentration Dependence of the - and -Processes for Alcohol-Water Mixtures

We performed broadband dielectric measurements for triethylenelgycol-water mixtures with various water contents in the frequency range between 1 muHz and 30 GHz in the temperature range between 130 K and 300 K. For the lower temperature range, the - and -processes were observed for each mixture. The...

Description
Summary:We performed broadband dielectric measurements for triethylenelgycol-water mixtures with various water contents in the frequency range between 1 muHz and 30 GHz in the temperature range between 130 K and 300 K. For the lower temperature range, the - and -processes were observed for each mixture. The -process depends on the water content. The -process for lower water content relates to the local motion of solute molecules and for higher water content mixtures relates to the motion of the water molecules.
